Disaster Recovery Using VMware vSphere Replication and vCenter Site Recovery Manager - Second Edition

Overview of this book

VMware vCenter Site Recovery manage is an orchestration tool used to automate disaster recovery in a manner that no other solution does. It is programmed to leverage array-based replication and VMware's proprietary vSphere Replication engine. The book begins by talking about the architecture of SRM and guides you through the procedures involved in installing and configuring SRM to leverage array-based replication. You will then learn how to protect your virtual machines by creating Protection Groups and validate their recoverability by testing recovery plans and even performing failover and failback. Moving on, you will learn how to install and configure vSphere Replication as a standalone disaster recovery solution. It also guides you through the procedures involved in configuring SRM to leverage vSphere replication. Finally, you will learn how to deploy and configure vRealize Orchestrator and its plugin for SRM and vSphere Replication.

Understanding datastore groups


A datastore group is a container that aggregates one or more replication-enabled datastores. The datastore groups are created by SRM and cannot be manually altered. A replication-enabled datastore is one whose LUN has a replication schedule enabled at the array.

The following diagram shows the multi-datastore datastore and single-datastore datastore groups:

A datastore group will contain only a single datastore if that datastore doesn't store files of VMs from other datastores. See the single datastore group conceptual diagram.

A datastore group can also contain more than one datastore. SRM aggregates multiple datastores into a single group if they have VMs whose files are distributed onto these datastores. For example, if VM-A has two VMDKs, each placed on Datastore-A and Datastore-B, then both these datastores become part of the same datastore group.

These datastore groups further aid in the creation of protection groups.
